  • Python get list of streams from video (audio/video)

    2 août 2019, par user972014

    I have a video file and I want to get the list of streams from it. I can see the needed result by for example executing a simple `ffprobe video.mp4 :

    ....
    
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661) ......
    
Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), ......
    
....

    But I need to use python and code that will work both on Windows and Ubuntu, without executing an external process.

    My real goal is to check whether there is ANY audio stream within the video (a simple yes/no would suffice), but I think getting extra information can be helpful for my problem, so I’m asking about the entire streams

    EDIT : Clarifying that I need to avoid executing some external process, but looking for some python code/library to do it within the process.

  • How can I extract images from an MPTS video(which has 4 videos in it) from each and every video using a single command ?

    21 octobre 2019, par geo-freak

    I have an MPTS video file, which has 4 videos in it. I want to extract images from each video and store them in a directory separately. I am using ffmpeg, I have seen references from previous solved questions.

    I used below command to extract frames.

    ffmpeg -threads 8 -i input.ts -s 400x222 -qscale:v 4 -start_number 0 -vf fps=1 /storage/frames/input_1//%d.jpg /storage/frames/input_2//%d.jpg /storage/frames/input_3//%d.jpg /storage/frames/input_4//%d.jpg

    But frames extracted only for first video in MPTS stream. How can I achieve using this using a single ffmpeg command ?

  • IE9+ not playing portait video in HTML5 video tag

    12 avril 2013, par ptrn

    For some reason I can't get IE9/10 to play video that is taller than wide, when using HTML5 video tags.

    Demo :
    http://s.l6.no/demo/video+html5/

    The demo shows one video scaled down from 1280x720, which plays perfectly fine in all tested browsers, and one video scaled down from 720x1280 which plays for all browsers but IE9/10.

    Tested and works for :

    • Chrome 26, Windows 7 64-bit
    • Chromium 24, Ubuntu 64-bit
    • Firefox 14, Windows 7 64-bit

    Tested and does not work for :

    • Internet Explorer 9, Windows 7 64-bit
    • Internet Explorer 10, Windows 7 64-bit

    I'm using FFmpeg to code the videos to MP4(x264) and WebM(VP8), with the current command dummed down to this :

    ffmpeg -i in.mp4 -vcodec libx264 -pix_fmt yuv420p -y -b:v 4000k out.mp4

    The lack of profile settings would be my first point, but since the other video is playing just fine, I can't see why it should matter.

    Any ideas ?

    Edit : soft rotating the video isn't really an option, as the user is to be able to download the video to play offline. I could transcode an extra version just for IE, but come on, there's gotta be another way, no ?
